Obviously there is something I haven't set up properly BUT with so little information available about setting up anything within Harbour (or HMG) it becomes a hit and miss effort followed by long, fruitless Google searches.

I should point out that I *can* compile and run code from the SAMPLES folder using the Build64.bat file, so obviously the command line environment is set up OK - just not the IDE environment.

Any thoughts/help please?

Edit - I should have mentioned - this is simply using tutor08 from the hmg.3.3.0/samples folder - so nothing special about it)

I mentioned in the OP though that I *can* run and build HMG apps from the command line using the build64.bat file so, although I didn't specifically say so, I *have* installed the 64 bit libs etc. and followed the instructions in the 64bit threads as best I can.

The problem is in the HMG IDE only - although 64bit version is selected from the main menu barf, it is obviously looking for 32 bit libs and I can't find anything, in any documentation, that tells me how I can fix this. If there is another setting to be changed (path, lib setting etc although these have already been done) I can't find it stated anywhere.
